Research Progress and Methods of the Polymer Fatigue Test

阐述了聚合物疲劳研究的必要性和重要性。介绍了疲劳研究的一些基础理论,着重介绍了断裂力学、损伤力学在高分子聚合物疲劳研究中的应用。讨论了聚合物疲劳裂纹的萌生、扩展机理和研究方法。另外,介绍了几种常用的疲劳试验,以及试验中所需要注意的问题。展望了今后高分子疲劳研究的方向,并提出了在高分子疲劳研究中亟待解决的问题。

The importance and necessity of polymer fatigue research are described. It also provides some important theoretics and methods of the polymer fatigue progress, such as damnify mechanics and rupture mechanics. The principal and research method of polymer fatigue cracks are discussed. Then some testing ways and something need to be noticed in the testing is introduced. The research of fatigue mechanism is quoted, based on the which direction of research in fatigue of polymer is pointed out. At last, it advances some questions need to be solved in the future.
